### Beispiele

Beispiel #1 MongoDB\Driver\BulkWriteCommandResult::getUpdateResults() example

`<?php
$manager = new MongoDB\Driver\Manager;
$bulk = new MongoDB\Driver\BulkWriteCommand(['verboseResults' => true]);
$bulk->insertOne('db.coll', ['x' => 1]);
$bulk->updateOne('db.coll', ['x' => 1], ['$set' => ['y' => 3]]);
$bulk->updateOne('db.coll', ['x' => 2], ['$set' => ['y' => 1]], ['upsert' => true]);
$bulk->updateOne('db.coll', ['x' => 3], ['$set' => ['y' => 2]], ['upsert' => true]);
$bulk->deleteMany('db.coll', []);
$result = $manager->executeBulkWriteCommand($bulk);
var_dump($result->getUpdateResults()->toPHP());
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    object(stdClass)#16 (3) {
      ["1"]=>
      object(stdClass)#7 (2) {
        ["matchedCount"]=>
        object(MongoDB\BSON\Int64)#5 (1) {
          ["integer"]=>
          string(1) "1"
        }
        ["modifiedCount"]=>
        object(MongoDB\BSON\Int64)#6 (1) {
          ["integer"]=>
          string(1) "1"
        }
      }
      ["2"]=>
      object(stdClass)#11 (3) {
        ["matchedCount"]=>
        object(MongoDB\BSON\Int64)#8 (1) {
          ["integer"]=>

        }
        ["modifiedCount"]=>
        object(MongoDB\BSON\Int64)#9 (1) {

        }
        ["upsertedId"]=>

        }
        ["modifiedCount"]=>
        object(MongoDB\BSON\Int64)#13 (1) {
